SPECIFICATION forming part of LettersPatent N. 616,197, dated December 20, 18.98. i Application led February 19, 1896. Serial No. 579,847. .(Nu model.) v v To all whom it may concern:

Be it known that I, WILHELM MLLER, a subject of the Emperor of Germany, residing at Bremerhaven, Germany, have invented certain new and useful Improvements in Valves for Steam-Whistles, for which I have obtained a patent in Germany, No. 85,033, dated May 5, 1895, and in Great Britain, No. 17,361, dated September 1'7, 1895;) and Ido 'hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the 'art to which it appertains to make and use the same.

With steam-whistles it is often found that the sound does not come at once in its full strength and distinctness owing to the pres ence of Water Which collects in the valve-body and the tube-conductors through condensa= tion of steam. This condensed Water also freezesin very cold weather and prevents the whistle from acting properly.

This invention has for its object to so con'- struct the valve for operating the whistle that water of condensation normally has a vfree egress, and after the operation of the valve any water is automatically discharged.

In vthe accompanying drawings, Figure 1 is a vertical section of a valve for a steam-whistle acting' by high-pressure steam, and Fig. 2 is a vertical section of a valve for low-pressure steam. Fig. 3 is atop view and a section of the arrangement shown in Fig. 2 on the broken line wz.

In Fig. 1 the steam-conducting pipe is c'onnected to the valvefbox G by the flange F2 and the pipe for the whistle by the liange F. A third flange F3 serves for aflixing the valvebox.' S is a plunger, fitted horizontally in the box, which carries a piston-disk K, fitting closely to the inner surface of one side of the valve-box. Over the inner end-of the 'plunger S is placed the conical valve V, bored cen- I trally and provided with holes o in its body',

which serve as steam-passages. `In the central bore of the big valve slides the small conical valve V2 by means of a small projection extending from the plunger S2, on which the valve V2 is fitted. The plunger S contacts with this projection for the purpose of opening the small valve. A spring f is arranged between the piston-disk K and the valve V and a spring f2 between "the valve Vt andl the 'cover D of Fig.,1.

For the ejection 'of water of condensation lower end of which may b e connected to a The lever fer vstarting the valve is shown at h.

In Fig. 2 only a single conical valve V is used'in lieu of thetwo valves shown in Fig. 1. The valve here is not provided with holes S if pressed against it. A spring fa is arvalve V. A v

The action .of the valve, Fig. 1, is as follows: In the normal position the piston K steamtube above the valve through the chan nel H to the collecting-tank, so that any conby means of the lever h the Water-discharge channel H is first closed by the movement of the piston K. During this movement when the opening is covered about one-eighth of, an inch the cone-valve V2 and after it V are opened by means of the plunger S, which first comes in contact with the valve V2 and after that with V and allows steam to pass to the whistle to cause it to sound. After reL fj"2 and steam, and the discharge of water from the tube commences automatically by the return of the pistonedisk, owing to the liowing naturally atrst downward through the opened channel. In order to facilitate the discharge of condensed water out of the means of a flle the surface of the plungers S and S2 and to mount the whole valve someor water discharge.

The action of the valve construction in Fig. 2 differs from that of Fig. 1 by lifting only one conical valve V,'owing to the low pressure of steam for which this structure is destined. rllhe amount of energy lnecessary for the opening of the valve V does notez@ and steam "the channel H is provided, the
